'fication.

This invention relates to a feed mechanism to be employed in connection with the sooalled linotype-machines for supplying solid metal to the melting-pot to replace the molten metal discharged therefrom.

Among other objects it is the object of the invention to provide a new and improved mechanism for accomplishing this purpose which will be automatic and require no attention except at long intervals of time,which will be positive and efficient in operation, and which will be simple and inexpensive.

Afnrther object is to so construct the mechanism that it will be readily applicable to known linotype-machinessuch,for instance, as the Mergenthaler machine, described in Letters Patent No. 436,532, granted September 16, 1890.

A further object is to provide means for regulating the speed of feed relative to the discharge of molten metal from the melting-pot.

A further object is to so construct the mechanism and melting-pot that the former can be located wholly without the latter and the melting-pot be kept closed except at the moment of entrance thereto of a pig of metal.

A further object is to generally improve and simplify the construction of such mechanism.

With such objects in view the invention is embodied in the parts, arrangement, and combinations of parts hereinafter described, and particularly set forth in the claims.

In the accompanying drawings we have shown a form of mechanism embodying our invention, but desire it to be understood that we do not limit the improvements in their useful applications to the particular construction which for the sake of illustration we have therein delineated.

In said drawings, Figure 1 is a front elevation of mechanism illustrating the invention. Fig. 2 is a side elevation thereof.

Referring to the drawings, A indicates an (No model.)

inclined plane or slide in or upon which the pigs of metal to be fed to the melting-pot are placed and in or on which they slide by gravity toward the delivery-transmitter, (indicated at E.) The slide A is shown provided with side retaining flanges or pieces a. Any suitable support may be provided for the slide A to hold it in proper relation to the melting-pot of the machine with which the feed mechanism is to be used. In the drawings We have shown simply uprights a Journaled in brackets 0, conveniently supported by the slide at or near its lower end and located above the same, is a shaft G, to which is fixed at one end a gear-wheel 0. Fixed on said shaft between said brackets 0 is a delivery means in the form of a turnstile, comprising the separated spiders E and bars or rods F, connecting the ends of the arms of the spiders. This turnstile is rotated step by step and admitsone bar or pig of metal at a time to each of its sections in the course of each revolution and answers the double purpose of forcing the'pig admitted between its bars F forward to final delivery and holding back the other pigs on the slide A until proper time for their delivery.

Q indicates a shaft journaled in suitable bearings conveniently supported by the slide A beneath the same. On this shaft is fixed a gear-pinion D, which meshes with the gearwheel 0 for rotating the same. Also fixed on the shaft Q, but readily removable therefrom, conveniently at the end opposite the pinion D, is a ratchet-wheel B, and loosely fulcrumed on the shaft adjacent-the ratchet-wheel is a lever N, carrying a pawl L, engaging the teeth of the ratchet-wheel. The lever carries at or near its outer end an antifriction-roller T, adapted to be engaged to rock the lever on its fulcrum by a suitable means, such as a cam U. This cam may be one of the cams forming part of the operating mechanism of the linotype-machine, with which the mechanism is to-be employed. The lever at its inner end extends beyond the fulcrum and carries a set-screw J, adapted to engage a vfixed part, such as the slide A, and limit the downward movement of the outer end of the lever toward the cam U. By this means it will be seen the length of movement of the lever can be regulated, and consequently the amount of rotation imparted to the ratchetwheel B, thus adapting the latter to be moved the space of one or more teeth each time, according to the adjustment of the screw J.

At the end of the slide A and adapted to receive the pigs delivered therefrom by the turnstile is a tray II, which is eccentrically pivoted at h and which is so weighted as to normally maintain the substantially horizontal position indicated in full lines in Fig. 1. The tray when it has received a pig is thereby tilted, when the pig is precipitated by gravity onto an inclined way I, which leads to the melting-pot, (indicated at K.)

The melting-pot in the linotype-machine above referred to is moved backward and forward a slight distance during the casting part of the machines functions, and to permitthis motion of the pot without affecting the proper delivery of the pig thereto by the slideway I we have shown the latter constructed of a fixed section I, suitably supported, and a movable section S, which latter is attached to and moves with the pot K. Its free end is conveniently supported in proper alinement with the fixed section I by the support R. The pot K is provided with a freely-swinging door or gate M opposite the end of the slideway I, which the pig swings in on entering the pot and which immediately swings back to its normal position, closing the entrance to the pot, thus effectually keeping the entrance closed and avoiding the splashing of the molten metal from the pot and also assisting materially in retaining a uniform degree of heat in the pot.

In the construction shown the pinion D and gear 0 are proportioned as one to four, and the turnstile has four rods or bars F. Thus the gear-wheel O, and consequently the turnstile, makes one-fourth of a revolution to each revolution of the pinion D. The number of teeth in the ratchet-wheel bears a certain relation to the number of lines of type required to make the same weight of metal as the pig. For example, nonpareil, thirteen-em measure, requiresaratchet of fifty-eight teeth; minion, forty-eight teeth; brevier, forty-four teeth, &c. To meet this requirement, ratchets to .suit the several sizes of type will be supplied,

one of which will be replaced by another as the machine is changed for dilferent sizes.

If double-measure matter is to be set, the lever N can be so adjusted by the thumbscrew J, as above indicated, that the pawl will ride over two teeth at each return or downward movement of the lever and advance the ratchet the space of two teeth at its next forward movement.

The operation of the machine, it is believed, has been made clear by the above description.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
